彩超对妊高征孕妇胫后动脉血流检测的研究

目的 通过对孕妇胫后动脉血流指数的检测，为妊高征预测性诊断提供一条新途径。方法 运用彩色多普勒超声对正常妇女、正常孕妇和妊高征患者三组各30例的胫后动脉血流指数改变的对照研究。结果 ①妊高征组胫后动脉的收缩期峰值血流速度（S）、平均血流速度（MN）、峰值血流速度之比（S／D）分别高于其它两组（P＜0．01）。②三组胫后动脉内径变化无统计学差异。结论 妊高征患者胫后动脉血流指数的改变为本病的诊断提供了新途径，具有一定的临床参考意义，其中胫后动脉S、MN及S／D值为较好的观察指标。

Analysis on the Detection of PTA Blood Current of the PIH Pregnant Women by Means of the Ultrasonic Wave

ObjectiveTo provide a new method for the predictive diagnosis of PIH through the detection of the PTA blood flowing indexes of the pregnant women. MethodTo adopt the color Doppler ultrasonic wave the conduct the contrast normal pregnant women and PIH women of post-pregnancy 30 cases respectively. Results①The peak value flow rate of blood at diastolic period (short for D), the average blood flow rate (short for MN), the ratio of the peak value blood flow rate (S/D) for PIH group are higher than those for the other two groups respectively (P<0.01); ②There is no statistic difference in the changes of the PTA artery internal diameter between the three groups. ConclusionThe changes in the PTA blood flow indexes of the PIH patients provides a new method for the diagnosis of this disease, which is of some reference value. Such indexes as S, MN and S/D of the PTA are better targets for observation.
